Answer 1

Answer:

He will take to perform the journey of 450 miles in 9 days of 8 hours each.

Step-by-step explanation:

Given that:

A man can perform a journey of 275 miles in 4 days of 11 hours each. _______(1)

Let man will take to perform the journey of 450 miles in x days of 8 hours each. _______(2)

Formula used:

S1/(D1 × T1) = S2/(D2 × T2)

Where,

• S1 = Distance given in (1)
• D1 = Total days given in (1)
• T1 = Total hours given in (1)
• S2 = Distance given in (2)
• D2 = Total days given in (2)
• T2 = Total hours given in (2)

According to the question:

→ 275/(4 × 11) = 450/(x × 8)

→ 275 × x × 8 = 450 × 4 × 11

→ 2200x = 19800

→ x = 19800/2200

→ x = 9

Answer 2

Answer:

Given :-

• 1 man can perform 275 miles in 4 days of 11 hours each

To Find :-

how man days of 8 hours

each will he take to perform a 450 mile journey?

Solution :-

S1/(D1 × T1) = S2/(D2 × T2)

By putting value

275/(4 × 11) = 450/(x × 8)

275/44 = 450/8x

275 × 8x = 44 × 450

2200x = 19800

x = 19800/2200

x = 9
